GUIDE-BOARD FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 325,307, datedSeptember 1, 1885.

Application filed January $1, 1885. (No inodcLl 1"0 all whom it mayconcern:

Be it known that I, J OHN BARKER, of Lawrence, county of Essex, State ofMassachusetts, have invented an Improvement in Guide-l3oards forSpinning-Frames, of which the following description, in connection withthe accompanying drawings, is a specification, like letters on thedrawings representing like parts.

This invention has for its object to improve the construction ofguide-boards, whereby they are made more durable, and whereby thefriction on the yarn is reduced to the minillllllll.

Guideboards as now commonly used are provided with eyelets, some ofwhich are slotted and made of bone or porcelain inserted in holes madethrough the boards vertically, the eyelets being held in place bycement.

In accordance with my invention the guidehoard slotted at its edgeinward for the en trance of the yarn being spun is provided with pocketsor recesses cut into the same from its top side to receive smallcylinders of glass or equivalent vitreous material, and the upper sideof thesaid board, instead of being left exposed, as previously, beingprotected by a steel or metal plate, also slotted inward from one edgeto correspond with the slots in the guide-board, the said metal plateserving the purpose of not only holding the glass wearing-surfaces inplace, but also covering and protecting the top of the guideboard, theslotted plate preventing wear or injury to the board in the said slotseither by wear or by blows.

Figure 1 represents a sufficient portion of a spinning-frame to show theposition of the guide-board with relation to thespindles and rolls. Fig.2, on a larger scale, represents a guide-board provided with myinvention, the metal covering-plate being broken out opposite one of theslots to represent the glass cylinder, which is used as the wearingsurface or support for the yarn. Fig. 3 is a section of Fig. 2 in thedotted line a: as.

The framework A, bolster-rail B, liftingrail 0, the spindle D, flier E,spool F, rollerstand G, rolls H and I, and rail L are all in commonspinning-frames, so need not be herein described. I have shown such oldand common devices in order to illustrate the position of the hingedguide-board a, which it is the object of this invention to improve.

The guide-board a is slotted at its front edge, as at Z), and is boredthrough, as atb, to constitute a slit and eye for the reception of theyarn c which is being spun. The upper side of the guide-board isprovided with a recess, (2, which intersects the eye I), and 111 thisrecess is placed the cylindrical piece 6, of glass or other vitreousmaterial, that portion of the surface of the piece of glass referred towhich intersects and crosses the line of 1) serving as a rest or supportagainst which the yarn bears and over which it is drawn as it is spunand wound up in the usual manner. The upper side of the guide-board isprovided with a steel or hard-metal plate, connected therewith by screwsf, and the said metal plate is slotted from its front side inward, as atg, is rounded, as at g, and at the inner end of said slot 1 haveprovided an eye, 9 the inner rearwall of which in the dotted line so islocated back of a vertical line drawn to intersect the front edge of theglass support or guide 6. o

The guide or support 6 is so located with relation to the upper end ofthe spindle and the rolls H I that the yarn is kept from contact withthe metal plate f at the inner end of the notch therein, thus preventingthe same from cutting or fraying the yarn.

The metal plate f protects the wooden part of the guide-board, which isslotted for the reception of the yarn, and any roughness of the board isnot felt by the yarn, nor is the board in the slots liable to be injuredor roughened by blows, as when not protected by the plate. The plate falso acts to retain in place and cover the support or guide 6.

Instead of the flier E, I may use an ordinary cap without departing frommy invention.

I claim- 1. The guide-board slotted at b b and recessed longitudinallyat d, combined with the cylindrical supports or guides c, of vitreousmaterial, placed in the said recesses, substantially as described.

2. The guide-board slotted at b b and re- Intestimony.whereoflhavesigned my name cessed at d, and the vitreoussupports or rests to this specification in the presence of two sub- [0'0, laid in the said recesses and crossing the scribing witnesses.

all substantially as set forth.
